"The iPad Camera Connection Kit gives you two ways to import photos and videos from a digital camera: using your camera’s USB cable or directly from an SD card. iPad and the Camera Connection Kit support standard photo formats, including JPEG and RAW, along with SD and HD video formats, including H.264 and MPEG-4."

BUT, I would read the reviews! Importing is quirky and export not supported.

Is it possible to upload your pictures without an intermediate laptop etc?
